Model classification of stainless steel plates
Stainless steel plate models are divided into three types according to composition: austenitic stainless steel, ferritic stainless steel and duplex stainless steel. According to the purpose, it is divided into three types: corrosion-resistant stainless steel plate, heat-resistant stainless steel plate and wear-resistant stainless steel plate.
Model characteristics and application fields of stainless steel plates
1. Austenitic stainless steel plate
The main characteristics of austenitic stainless steel plates are good plasticity, toughness and weldability as well as high corrosion resistance. Common austenitic stainless steel plate models include 304, 316, 321, 309, 310, 201, etc.
Among them, 304 stainless steel plate is the most common model, with good corrosion resistance and ray resistance, and is widely used in equipment, chemical industry, food and other fields; 316 stainless steel plate is the model with the best corrosion resistance and is suitable for marine, Used in chemical industry and high temperature environment; 321 stainless steel plate has good high temperature resistance and corrosion resistance, and is suitable for high temperature resistant stoves, chemical equipment transportation and other fields.
2. Ferritic stainless steel plate
The main characteristics of ferritic stainless steel plates are high hardness and wear resistance, but poor plasticity and toughness. Common ferritic stainless steel plate models include 430, 409L, 436L, 439, etc.
Among them, 430 stainless steel plate is a commonly used ferritic stainless steel plate and is suitable for construction, home appliances and other fields; 409L stainless steel plate has good corrosion resistance and welding performance and is suitable for some machinery manufacturing fields.
3. Duplex stainless steel plate
The main feature of duplex stainless steel plate is that it has the weldability and good strength of austenitic stainless steel and the corrosion resistance of ferritic stainless steel. Common duplex stainless steel plate models include 2205, 2507, etc.
Among them, 2205 and 2507 duplex stainless steel plates have high strength and excellent corrosion resistance, so they are widely used in marine engineering, chemical industry, petrochemical and other fields.
Stainless steel plates come in a variety of models and uses. Different models of stainless steel plates have different characteristics and advantages. Suitable materials can be selected according to different application fields. Master the classification and characteristics of stainless steel plates and be able to better purchase and apply stainless steel plates.
